This is how I do it. Instead of writing a large amount, I just make it generate one function at a time.

I dont want it to replace me, I replace reading the docs and googling or repetitive tasks.

Its a hit or miss sometimes but I get to review every snippet.

If I would generate alot of code at once like for a full project I would get brainfuck reviewing it.

I keep my normal development flow and iterate, no waterfall
